- PR #31384 fixed an issue where the coinbase transaction weight was being reserved in two different places.
The fix ensures that the reservation happens in a single place.
- This specifies how many weight units to reserve for the coinbase transaction.
- Upgrade note: the default of `-maxcoinbaseweight` ensures backward compatibility for users who did
not override `-blockmaxweight`.
- If you previously configured `-blockmaxweight=4000000` then you can
safely set `-maxcoinbaseweight=4000` to maintain existing behavior.
- Bitcoin Core will now **fail to start** if the `-blockmaxweight` or `-maxcoinbaseweight` init parameter exceeds
the consensus limit of `4,000,000` weight units.
